Android Fragment Scan

Before you can use your PandwaRF device, you need to connect it to your smartphone. First scan for all nearby PandwaRF devices using the "SCAN" tab of the application.

If there is a PandwaRF nearby, you will see something like this:

In this snapshot, we can see 2 PandwaRF advertising and available for connection.

You have 2 options for connection:

• Reconnect if link loss: will automatically attempt to reconnect the dongle if there is a disconnect (eg. due to app running in the background).
• Connect refreshing the cache: the Android Bluetooth device cache will be cleared before reconnection, forcing all the BLE services and characteristics to be re-fetched from PandwaRF. Use this option in case you have some spurious disconnections just after you connect the PandwaRF. This option is in theory slower than connecting using the Android cache.

[Edit 17/06/2019] Starting Android App 1.5.4, these 2 options have been moved to App settings.

Once you have decided which PandwaRF to connect to, click on it. The icon in the title bar should change according to the connection status:

• : Disconnected. No BLE or USB connection.
• : BLE Connected. Connection has been established, and BLE services and characteristics are being enumerated. PandwaRF is not useable yet. This state can last up to 3s.
• : BLE Ready. PandwaRF device is ready in Bluetooth Low Energy mode. All features are available.
• : USB Ready. PandwaRF device is ready in USB mode. All BLE features are not available. Almost all RF features are available.

You will be automatically redirected to the Bus Service tab.

Note: You can stop & restart the scanning at any time.
